Make Ethereum massively scalable today with delayed computations

Suppose you're writing a contract which involves a huge amount of participants. As an example, think of an online, blockchain-based Trading-Card Game with tournaments. How would you program a playCard function? You might be thinking of something like this:

function playCard(uint player, uint card){
    ...
    else if (card == PROFESSOR_OAK){
        // shuffles the player's hand on his deck
 shuffleHand(player)
